Where applicable, Norweco septic tanks have been approved by both IAPMO and CSA.

Please consider the following features when you are looking to purchase a septic tank and you'll find that Norwesco tanks will exceed your expectations when it comes to performance and longevity.

Ease of InstallationFor septic system replacement and new home construction, Norwesco's polyethylene septic tanks are designed for durability and quick, easy installation. Any Norwesco septic tank can be transported to the job site in a pickup truck and carried by just two people. This enables you to install the tank on your schedule.

Excellent Chemical ResistancePolyethylene is unaffected by soil chemicals and by the chemicals and gases present in sewage, so Norwesco septic tanks will not rust or corrode and require no additional coatings as other tanks do. Norwesco's strict quality guidelines ensure an environmentally safe septic tank.

Single or Double CompartmentOur 750, 1000, 1250 and 1500 gallon tanks are available as single compartment or double compartment tanks (2/3 - 1/3). Prior to installing any septic tank, you should check with your local health department for specific requirements that your county or state may enforce.

Pre-Plumbed / Ready for InstallationNorwesco septic tanks (750 gallons and larger) are shipped to you ready for installation. Our pre-plumbed tanks include tee assemblies installed at the inlet and outlet. Tees are sized/cut according to each state code so the tank that you receive will be ready for installation.

Watertight LidNorwesco septic tanks come outfitted with a domed lid. This improved design is significantly stronger than other lid designs. When leaving our factory the lid is attached to the tank with four stainless steel screws and comes standard with a foamed, polyethylene gasket between the lid and the tank. The gasket provides a watertight seal at the lid area.

Accessories AvailableManhole extensions and lid-riser combinations are available to bring tank access to grade and to meet code specifications.
